Feast of the Divine Maternity – Second Sunday in October or 11 October:
The object of this feast is to commemorate the dignity of the Mary as Mother of God. Mary is truly the Mother of Christ, who in One Person unites the Human and Divine Nature. This title was solemnly ratified by the Council of Ephesus on 22 June, 431.
It was long celebrated in Portugal, where the Maternity of Our Lady was declared a feast on 22 January in 1751, at the request of King Joseph Manuel. The feast, granted to the Dioceses of Portugal, Brazil, and Algeria, was assigned to the first Sunday in May. In the following year it was extended to the Province of Venice; in 1778, to the Kingdom of Naples; in 1807, to Tuscany. It was finally instituted in 1931 by Pope Pius XI in view of the fifteenth Centenary of the Council of Ephesus.
At the same time the Pope ordered, at his own cost, the restoration of the Marian mosaics in Saint Mary Major, much decayed through age. He issued an encyclical letter, “Lux veritatis.”In this, among the objects of the new festival, is named one truth that was particularly close to the heart of Pius XI, “…that Mary, who is loved and revered so warmly by the separated Christians of the East, would not suffer them to wander and be unhappily led further away from the unity of the Church and, therefore, from her Son, whose Vicar on earth we are.”
At present the feast is not found in the Universal Calendar of the Church but nearly all Diocesan calendars have adopted it.
St Pope John XXIII (1881-1963) (Optional Memorial) Angelo Giuseppe Roncalli became the 261st successor of St Peter, He reigned from 28 October 1958 until his death on 3 June 1963.
